Ae o le-2-ene o se alkene acyclic e fa atomika kaponi. O le alkene sili ona faigofie o loʻo faʻaalia cis / trans-isomerism (faʻapitoa foi (E / Z) -isomerism); o lona uiga, o loʻo i ai o ni isomers geometric e lua cis-ae-2-ene ((Z) -ae-2-ene) ma le trans-ae-2-ene ((E) -ae-2-ene).
O isomers e lua e matua faigata lava ona vavae ese e ala i le faʻamama ona o le vavalalata o latou mea faʻafefe (~ 4 °C mo cis ma ~ 1 °C mo trans[5]). Ae ui i lea, e le manaʻomia le teteʻa i le tele o fale gaosi oloa, aua e tutusa uma le isomers i le tele o tali manaʻomia. O se fa'afefiloi fa'apisinisi masani ae-2-ene o le 70% (Z) -ae-2-ene (cis-isomer) ma le 30% (E) -ae-2-ene (trans-isomer). Butane ma but-1-ene o mea leaga masani, o loʻo i ai i le 1% pe sili atu i faʻafefiloi fale gaosimea, lea e iai foʻi ni vaega laiti ole isobutene, butadiene ma le butyne.
